Driving can be tricky, depending on where you live and intend to drive. I came from a small town and driving is pretty easy, though traffic has significantly increased since and there are quite a few bad drivers out there. If you aren't normally a nervious or easily distracted person, driving won't be too difficult to learn. My suggestions is definitely take a driving class even if not compulsory. Learn the rules of the road, learn to anticipate what other drivers may do, espsecially if they come up to an intersection...so many will not want to even stop so they can get ahead, even if you are the only car in sight for miles.
Keep distractions minimal in the car (ie turn off cellphone, no texting (I wouldn't even use the hands off headsets, just turn the phone off. If you are focusing on talking to somebody you aren't focusing on the road and everybody else). Definitely avoid eating or drinking in the car especially in city driving. Not so bad when you are out on the open road where traffic is light. KNow your blind spots too...(a class will teach all these things too)
I love driving and it gives one a great sense of freedom as you can go anywhere you want at any time (as long as you have access to or own a car etc.) but a car isn't a toy and so many people drive them like they are...or they want to get 'there NOW' and won't tolerate you going only 20 km over the speed limit. What bugs me most about driving is headlights. I see far better without them coming towards me or sitting on my backside so close my night vision is totally shot. When I drive at night I prefer very late at night, such as after midnight...less traffic and most of the yahoos are gone and its just the truck drivers... But this is when I travel to some large city. City driving is much different and I really don't like bumper to bumper traffic. Thus I avoid the main express ways when I can.
